It should be noted that, in this embodiment, the filter member is a filter screen, and the filter screen plugs the pair of seawater entering the liquid inlet at the liquid outlet of the liquid inlet pipe 100 to filter, so that the structure is simple, and the filtering effect is good.
Preferably, the cross-sectional area of the outlet header 200 is 7 or 8 times the cross-sectional area of the outlet. By defining the cross-sectional area of the main outlet pipe 200 to be 7 times or 8 times that of the outlet, when pressurized seawater flows along the main outlet pipe 200 to the sub-outlet pipe 300, since the cross-sectional area of the seawater flowing through the pipes is reduced, the flow rate of the seawater at the outlet with a smaller cross-sectional area needs to be increased in the same time, so that the pressurized jet effect on the seawater is further improved, the seawater can be discharged with a larger flow rate, and the reaction force on the ship is further improved.
The specific structure of the liquid outlet sub-pipe 300 will be described with reference to fig. 3. As shown in fig. 3, the liquid outlet pipe 300 is further provided with a connecting section 320, one end of the connecting section 320 is connected with the liquid outlet main pipe 200, and the other end of the connecting section 320 is connected with the straight pipe section 310. By arranging the connecting sections 320 to be respectively connected with the straight pipe sections 310 and the liquid outlet main pipeline 200, the change of the flow velocity of the seawater in the flow passage with the changed cross sectional area can be buffered, and the damage to the straight pipe sections 310 caused by the sudden increase of the flow velocity of the seawater can be avoided.
Specifically, as shown in FIG. 5, the preset length of straight tube section 310 is L 1 ，L 1 And is more than or equal to 300mm. Because the circulation direction of the seawater in the circulation process is not a straight line, the seawater can collide with the pipe wall, if the pressurized seawater is directly discharged along the liquid outlet, larger turbulence can be generated, the reaction force of the ship is reduced, the seawater can flow in the straight pipe section 310 with the length of at least 300mm before the seawater is discharged along the liquid outlet by ensuring the length of the straight pipe section 310 to be at least 300mm, and the pressurized seawater is effectively eliminated from flowing through the circulationTurbulence generated in the process ensures that the injection angle of the pressurized seawater is consistent, and further ensures that the reaction force on the ship is stable. Note that, in the present embodiment, the preset length of the straight tube section 310 is L 1 In other embodiments, the length of the straight tube section 310 can be adaptively adjusted according to actual requirements, only the length of L is required to be ensured 1 Not less than 300mm, and the embodiment is not particularly limited.
In the present embodiment, the flow rate of the pressurized seawater discharged along the outlet can be maintained between 28m/s and 32m/s by setting the cross-sectional area of the outlet header pipe 200 to 7 or 8 times the cross-sectional area of the outlet and adjusting the output power of the output device. Pressurized seawater with discharge flow rates in the range of 28m/s to 32m/s is the result of multiple tests and comparisons performed by the applicant. Specifically, in the present embodiment, the flow rate of the seawater discharged under pressure along the liquid outlet is 30m/s. In other embodiments, the flow rate of the pressurized discharged seawater along the liquid outlet can be adjusted within the range of 28m/s to 32m/s according to the actual situation, and the embodiment is not particularly limited.
As shown in fig. 2 and fig. 5, the preset angle includes a first inclination angle α and a second inclination angle β, where, an end of the straight pipe section 310 connected to the connecting section 320 is taken as a base point, a radial vertical plane corresponding to the base point is taken as a reference plane, the straight pipe section 310 horizontally rotates along the base point by the first inclination angle α with respect to the reference plane toward the rear of the ship, the first inclination angle α=15°, an end of the straight pipe section 310 connected to the connecting section 320 is taken as the base point, the radial vertical plane corresponding to the base point is taken as the reference plane, the straight pipe section 310 vertically rotates along the base point in the reference plane toward the lower of the ship by the second inclination angle β=15°. The reaction force that can be applied to the vessel at an optimal angle by tilting the straight pipe section 310 downward by 15 deg. and backward by 15 deg. with respect to the vessel to allow pressurized seawater to be discharged is a result of many tests and comparisons made by the applicant.
It can be appreciated that the ship bow side pushing system 1000 provided in this embodiment is applicable to various situations in which the application of the side thrust to the ship is realized by the pressurized injection of the seawater in the ship.
